Proportional Relationships in a Table (Part 2)

The video tutorial explains how to determine if a relationship in a table is proportional by testing for equivalent ratios. It uses an example involving chocolate and pretzels to demonstrate the process of checking proportionality by comparing decimal values of ratios and using cross products. The lesson concludes by summarizing the methods to test for proportionality in a table.

What is the first step in determining if the relationship in a table is proportional?

• Check for equivalent ratios

• Identify the largest number

• Find the sum of all values

• Calculate the average

How do you verify if two ratios are proportional using decimals?

• By multiplying the ratios

• By converting them to decimals and checking for equality

• By adding the ratios

• By subtracting the smaller ratio from the larger one

What is the decimal value of the ratio 6/8?

• 0.95

• 0.65

• 0.75

• 0.85

What method can be used to test if 9 ounces of chocolate for 12 pretzels is proportional to 12 ounces of chocolate for 16 pretzels?

• Cross products

• Addition

• Subtraction

• Division

What is the result of the cross product of 9 and 16?

• 128

• 144

• 152

• 136
